Tekky Synths THriCe

Although the full version of THriCe costs €30, there's also a free iteration that has most of its features (only filter modulation by the 3 StepSeq LFOs is missing). What we're dealing with here is a 3-oscillator synth, with each oscillator having its own multiband filter. There's also an internal sequencer and an FX section.

Tactile Sounds TS-808

TS-808 is - wait for it - an emulation of the Roland TR-808 drum machine (you got the subtle hint didn't you?). As you probably know, it isn't the first, but Tactile Sounds points out that this is a proper synth rather than a sampler, and that you have more sound-shaping controls than on the original hardware. You've got eight outputs to play with, too.

SAR VSTs Logana

A rather fine-looking freebie from SAR, Logana uses a physical modelling engine to emulate analogue-style sounds. It's got three oscillators, a noise generator, a mod matrix and mod envelope, an LFO, a low-pass filter, an amplitude envelope and overdrive distortion.

Betabugs Oszillos Mega Scope

When the time comes to start fine-tuning your mix, Oszillos Mega Scope might be able to help you out. It's a BPM-synced oscilloscope with support for multiple inputs. Waveforms can be displayed separately or as one coloured waveform.
